Filed: 1983-04-19
Abstract: PURPOSE:To enable high speed and high-accuracy measurement of coefficient of optical rotation by driving a pulse motor for rotating light-detecting element in accordance with strengths of light passed through a light-detecting element. CONSTITUTION:A pulse attenuator 19, emits high-speed pulse signal and low- speed pulse signal according to an input signal from a VF comvertor 14. When an angle theta between plane of polarization of light-detecting element 6 and that of specimen is large and intensity of light incident to a photomultiplier 8 is high, a high-speed pulse from the pulse-attenuator 19 is emitted basing upon a comparative result of standard electric potential and input signal electric potential in a level monitor 18 through a switch 20 and a pulse motor 7 bring the light- detecting element 6 into high-speed rotation. When the angle theta becomes small, a low-speed pulse is emitted, the pulse motor 7 bringing the element 6 into low-speed rotation and at theta=pi/2, the rotation is stopped. A signal from the switch 20 is emitted into an up-down counter 15 also at the same time, displaying the angle of rotation of specimen on a display board 17.

Title: Side weir in twin roll type strip continuous casting machine and twin roll type strip continuous casting method using side weir
Inventor: AO YOJI
IPC: B22D11/06
Filed: 1995-03-29
Abstract: PURPOSE: To extend the service life of a refractory layer by pressing a backup plate against the end surfaces of twin rolls with a pressurizing device, arranging a refractory layer on the backup plate and arranging metal-made sliding protrusions having thickness lower than the refractory layer to the outside of the refractory layer. CONSTITUTION: The refractory layer 5 is pressed against the twin rolls 3, 3' through the backup plate 1 with the pressurizing device 2. The refractory layer 5 is scrubed with the end surfaces of the twin rolls by rotation of the twin rolls 3, 3' and worn. The end surfaces and the surface of the refractory layer 5 are mutually fitted. When the wear of the refractory layer 5 proceeds, the metal-made sliding protrusions 6 reaches the end surfaces of the twin rolls 3, 3'. The protrusion 6 serves as a spacer because this is difficult to wear in comparison with the refractory layer 5, and the wear of the refractory layer 5 thereafter is restrained. The end surfaces of twin rolls 3, 3' are kept in close contact with the refractory layer 5 and the insertion of the molten metal is not caused. Therefore, the service life of the refractory layer 5 is extended.
